#include <stdlib.h>
#include <stdio.h>
#include <time.h>
/* prints a random number in the range 0 to 99 */
int main(void)
{
randomize();
printf("Random number in the 0-99 range: %d\n", random (100));
return 0;
}
有如下错误:
warning C4013: 'randomize' undefined; assuming extern returning int
warning C4013: 'random' undefined; assuming extern returning int
Linking...
Text1.obj : error LNK2001: unresolved external symbol _random

为什么呀,在TC里就可以运行的

randomize()和random()是VB里的函数吧？
C里面的随机函数是
初始化:srand (unsigned int);
产生随机数:int rand();
要使用随机数，要包含头文件#include <stdlib.h>
一般再包括#include <time.h>
初始化的时候这样子:srand(time(0));
